Question

isn't the least count of time 0.2?

Answer 1

for what? a lab experiment?

Answer 2

yess for a lab experiment!

Answer 3

it depends on how your measurements are set up

Answer 4

what were you measuring? how were you measuring it? and why is it important?

Answer 5

huh?its imprnt for my phy xam! measuring time from stopwatch!

Answer 6

what is changing with time? or are you measuring reaction time? or something else?

Answer 7

in theory, time can be divided into infinitesimally small quantities, but your stopwatch probably counts time in 0.01 second intervals.

Answer 8

or maybe 0.001 second intervals

Answer 9

but unless I can se the procedure or data from your experiment I don't know if the least count of time is 0.2.

Answer 10

thankYou @Peter14

Answer 11

I'm sorry I couldn't answer your question

Answer 12

When using a stopwatch to count time, you usually have an error associated with your reaction time, which is usually around 0.16 seconds (0.12 if you're lucky). So, yeah 0.2 seconds is a valid minimum count time. Although you could go for less if you try calculating your reaction time.

Answer 13

Thankyou! i found out that you both are correct! @Lessis and @Peter14
